A CORPORATION OF CONNECTICUT LIGHTING FIXTURE Application filed April23,

The present invention relates to a lighting fixture, and is moreparticularly directed to a semi-indirectlighting fixture for generalillumination.

The present invention contemplates a lighting fixture in which thesuspended parts of the fixture are so arranged that they may be readilydisconnected from the lead wires so as to facilitate installation of thefixture,

removal or change of the fixture, and refinishing or cleaning thefixture.

The present invention contemplates a fixture in which a plurality oflamp socket supporting arms extend downwardly through a central hole ina large toroidal shaped glass shade so as to support the lamp socketsunderneath the shade to position lamp bulbs inside the shade. Thisprovides a semi-indirect lighting fixture in which the lamps areconcealed by the glass shade.

A further object of the invention is to provide a chandelier wherein anannular glass shade, which houses a plurality of electr1c lamps but notthe lamp supportlng arms, may be readily removed from the supports whenthe fixture is detached from its suports.

Another object of the invention is to pro vide a chandelier wherein aplurality of lamps extend downwardly and outwardly from a body andsupport a glass shade which shade maintains the arms in proper positionrelative to one another.

A further object of the invention is to provide a lighting fixture whichcan be detachably supported from suspending means and at the same timedetachably electrically connected to the fixture supply wires.

Other and further objects of the invention will appear as thedescription proceeds.

The accompanying drawings show, for purposes of illustrating theinvention, one of the many possible embod1ments in which it may takeform, it being understood that the drawings are illustrative of theinvention rather than limiting the same.

When the lighting fixture contemplated by the present invention is madeup in the form of a chandelier for house and store lightin it will besupported on some form of sus pension element such as a rod, cord, orchain. As shown in Figure 1, the fixture is pro- Vided with a loop 10carried at the lower end of a fixture chain 11. The wiring for thefixture is carried down along the chain in the usual manner and passesthrough a hole in the loop. The lower end of the loop 10 is threaded asindicated at 12, in Figure 3, to support a hollow spindle 13, and asmall hook or loop 14 is threaded into the lower end of the spindle. Thelead wires from the fixture pass down through the spindle l3 and looplei and are connected to plug receptacles 15. A cover member 16 iscarried on the rim 17 of the spindle 13. This construction permitsconnecting up the shade and lead in wires for the fixture with thehouse-lighting wires so that the house wiring may be inspected after thefixture has been connected to the circuit.

A body 18 is provided with a centrally arranged hook 19. As here shown,the structure for supporting this hook from the body is in the form of aspindle 20 passing through a hole 21 in the body member 18 and through aplate 22, and threaded into the lower end of the hook 19 as indicated at23. The plate 22 rests on the flange of body member 18.

A plurality of tubular chandelier arms 24 are supported from the bodymember 18. As here indicated, the upper ends of these arms are threadedto receive nipples 25 which pass through holes in the body 18. Thesenipples are locked in place by nuts 27 placed above and below the bodymember 18. The lower ends of the arms 24 are bent out- 111g cup 29.

wardly as indicated at 28 and each arm passes through the side wall of asocket hold- Side opening lamp sockets 30 are mounted in the socketholding cups and are fastened in place by ornamental knobs 31 threadedonto stems 32 carriedv in the lamp sockets.

The fixture wires 33 pass from the side opening lamp sockets 30 upthrough the tubular arms 24 and out into the chamber provided by thebody'member 18. The fixture wires 33 are brought together and connectedto plugs such as illustrated at 34. The use of two receptacles 15 and.two plugs 34 is preferred as it is possible to make this part of thefixture more compact than if an ordi. nary convenience receptacle wereused. The chandelier is also provided with a glass shade 40. Asindicatedin the" drawings, this shade is of U-shape orsemi-circularcross section. The surfaces of the shade are formed assurfaces ofrevolution of a semicircular (or substantially semi-circular)curve about the vertical axis of the shade. This provides an annularshadeot toroidal shape. It is provided with regularly spaced holes 41which are adapted to receive the upper ends 42 of the socket cups 29.The central hole or aperture 42 in the annular shade is sufficientlylarge to accommodate the fixture arms24. It is alsolarger in diameterthan the body 18.

In assembling the fixture, the glass shade is passed onto the metalparts of the'fixture from above, and, when it has been brought to theposition indicated in Figure 1, it will be supported on the flanges 43on the socket cups 29. Whether or not it rests on the -chandelier arms,would be a matter depend ing upon the shape of the arms.

The lower part of the fixture may he installed by inserting the hook 19intov the loop or hook 14 after which the plugs 34- may be inserted intothe receptacles 15 and the cover 16 brought down into place against thebody member 18.v The weight of the fixture will be carried through thehook andloop while the wiring will be effectively installed andconcealed. The fixture will hang true from the loop 14. It can be takendown at any time by going through the reverse operations. The glassshade will conceal. the

itto 'be understood. that the particular form shown is but one of themany forms. Various modificat on-s and changes be ng pose sible, I donot otherwise limit myself in any way with respect thereto:
